The practice of this Kriya is inside the cranium, in the third circuit. The cranium is the divine kingdom. The real “You” is hiding inside the pituitary, constantly feeling the power of God as soul dwelling in your body. This is the perfection of Third Kriya.
During meditation the only perception is of the triple divine qualities rotating inside the cranium. The devote feels as if his soul is separated from the body and is floating in a vacuum. In this stage the meditator feels that the soul is all pervading and is going up to high heaven. You see the whole world inside your cranium. At your crown, thousand petals of light rotate inside your brain and illuminate your soul.
In anything you do, even while engaged in busy worldly activities, you will feel that some super power is doing the work through you. Yet you will remain detached and be able to avoid any negativity that comes. The samadhi of the Third Kriya is tanumanasa samadhi. This means the mind is not roaming in the biological sense. It has achieved the introvert stage, where the ordinary mind has been transformed into knowledge. It is still roaming, but only in the philosophical sense, as it perceives God-consciousness even as it remains in the world
